SJ Partners, LLC with operating partner Aaron Kleinhandler and his investment affiliate ASLK Investments LLC, Northcreek Mezzanine, and Everside Capital Partners, LLC have made an equity investment into CentralBDC, LLC, a Boca Raton, Florida based Outsourced Business Development Company that provides lead management services to auto dealerships nationwide. The new Company will be named CentralBDC, Enterprises, LLC (CentralBDC).

CentralBDC is the automotive industry’s fastest growing outsourced BDC Company. CentralBDC’s proprietary technology coupled with its highly trained and motivated employees currently support many of the largest dealerships and dealership groups nationwide as their full-service BDC for sales, equity-mining, appointment setting and customer service. Its management team has over 50 years of experience in the automotive industry. Benjamin Shamsizadeh will continue to help lead the Company as President and will be joined by Aaron Kleinhandler who will become the Company’s new CEO.

“I was looking to find a collaborative partner to help take us to the next stage of growth, and I believe I found that in Aaron and the teams from SJ, Northcreek, and Everside,” says Benjamin Shamsizadeh, the Founder of CentralBDC. “I am eager to help continue leading the business and see tremendous value in leveraging their experience to guide our growth strategy.” Enterprise Bank & Trust provided a senior term loan.

“I am thrilled to be partnering with Benjamin and the rest of the CentralBDC team,” says Aaron Kleinhandler who led the investment. “CentralBDC is well positioned to capitalize on a massive market and strong underlying demand tailwinds for our services. We believe that their technology-enabled, highly scalable delivery model is differentiated from smaller competitors and will allow the business to capture an outsized share of the growing market.”

“The partnership with Aaron and Benjamin is an exciting new phase for CentralBDC,” adds Scott Johnson, founder of SJ Partners. “This is our second investment with Aaron. Under Aaron’s leadership, that previous investment, Spectrio, experienced enormous growth from startup to approximately $40M in EBITDA driven by 38 add-on acquisitions. We now see an opportunity to deliver solutions to a much larger set of clients and to continue growing the organization to better meet the needs of those clients as well as serving as a platform to acquire others in this exciting space.”
